To a suspension of N-(3-(5-(4-chlorophenyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluorophenyl)-propane-1-sulfonamide (0.2 g, 0.41 mmol) in dioxane (15 mL) were added benzoyl chloride (57 mg, 0.41 mmol) and triethylamine (0.14 g, 1.38 mmol). The reaction was stirred at rt for 1 h, then concentrated in vacuo. The residue was purified by a silica gel column chromatography (hexane/EtOAc (v/v)=4/1) to afford the title compound as a white solid (0.14 g, 55%). The title compound was characterized by LC-MS and 1H NMR as shown below:
